There are many wonderful things about natural hardwood flooring. One is that you can refinish it over and over again, giving it a new lease on life each time you do it. Of course, there’s a downside. Refinishing takes time and effort—and if you a hire a pro, the work doesn't come cheap. Minwax Hardwood Floor Reviver offers a nice, affordable compromise between on the one hand, doing nothing and on the other hand, going all the way. The product doesn’t magically heal damaged flooring, but for dull, lightly scratched, or worn-looking hardwoods—simply put, for hardwoods that show signs of wear and tear—lots of folks say there's no better product. Available at Amazon; $20.97.
